Document gets indexed incorrectly in .doc

[NitzaAg]

Describe the bug

We are indexing a .doc having page numbers in the headers. After indexing, we see a number at the beginning of the indexed document, which we presume belongs to a page number in the document's headers. We don't see any other header getting indexed. This job indexes the .doc and gets a 4 at the beginning of the indexed document.

Is there a way to prevent headers from getting indexed? We noticed that for this document, saving the .doc as .docx surpassed the error.
